Both mutants were crossed to the parental A10.1 line, and the resulting progeny of the selfed F1 individuals displayed the expected Mendelian 3:1 ratio for a single locus recessive allele (31:16; P [χ2, 1 df] = 0.15 and 40:10; P [χ2, 1 df] = 0.41], respectively).

Introduction to Inheritance Symbols and Terminology Worksheet: A 2 - page worksheet with 20 opportunities for students to choose appropriate letters to denote dominant and recessive alleles, name homozygous and heterozygous genotypes, determine phenotypes from genotypes, and apply the Principle of Segregation.

Dogs with a dominant KB allele have black coats regardless of their genotype at the A locus; the coat color of dogs homozygous for the recessive ky allele are controlled by A locus.

Testing for this mutation along with Ay and recessive black (a) also allows for the identification of aw alleles in those breeds where it is present.In breeds where only the Ay and at alleles are present, the Ay test can be used to see if the fawn / sable dog is Ay / Ay (homozygous) or only has one Ay (heterozygous).

Genetic transmission of deafness in dogs with the recessive alleles of this pigment gene, such as the Dalmatian (which is homozygous for sw), is less clear.

The relatively high estimates of the frequencies of the unfavourable recessive alleles in each breed, especially for hip dysplasia, suggest that it would be possible to gain considerable genetic progress by selection against a major gene.

Although the visual effect can be the same, it is easy to confuse this with the subtle hint of bronze (liver) that shows through in coats of some black dogs that carry an incompletely - masked recessive allele (one of the gene pair) for «a dilute» such as liver - chocolate.

While genome - wide association studies (GWAS) are an efficient approach for the identification of recessive alleles, they require several unrelated affected individuals [17]--[19].
